What's most frustrating and rewarding about entrepreneurship/innovation?

Making decisions that turn out to be wrong decisions for your company can be frustrating. but entrepreneurship is a journey and you learn from your mistakes.
The opportunity to take an idea and see it developed into a service or a product that people use is extremely rewarding.

What's the No. 1 mistake entrepreneurs make?

Overbuild. Running and implementing a lot of cool features and not developing a product that the target customers can understand from the get-go. Many thinks that adding many features from the beginning will make them unique and separate them from their competition, but in fact in most cases, it hurts them since it takes time and money to build it before getting the actual feedback from the market.

What are the top three lessons you've learned as an entrepreneur?

Lesson 1- Do not overbuild. This was my first big mistake and I certainly learned from it. We had so many great ideas and ran an implemented most of them but changed our direction before it publically launched.

Lesson 2- Work with a focus group. Start with the core product and test it on a small group of users. Collect their feedback and go back to the drawing table to make necessary changes.

Lesson 3- Believe in your idea even if the initial feedback is not as what you expected but don’t ignore the obvious.
